This technical note discusses some of the key offshore applications for oil-on-water monitoring and thickness detection. Leakwise systems have over 18 years of experience supplying reliable monitoring to major petroleum and power companies in offshore and onshore applications.

Designed for Marine Applications

The Leakwise ID-227 wired and ID-227WL wireless systems consist of a sensor mounted on a wave rider buoy. This enables the detecting antenna to function at the liquid/air interface despite liquid level fluctuations due to waves and tide. Both systems are designed to install offshore, monitor oil on water on waves up to six feet (two meters) high and in currents up to two knots, and survive extreme sea conditions. An optional automatic cleaning system ensures continuous, maintenance-free operation in waters with high algae growth, seaweed, barnacles, etc.

The ID-227WL has the wireless capability to communicate via point-to-point radio or via GSM cellular network. If required, a satellite communication can be supplied. The ID-227WL is a stand-alone unit with autonomous solar power supply (see Figure 1). The system has alarm and control capabilities via dry contact relays and 4-20mA signal output. The ID-227 wired model (see Figure 2) is supplied with a floating cable and can be connected to its signal processor and controller located up to 1000 meters away. This system also has alarm and control capabilities via dry contact relays and 4-20mA signal output.

Background
Older generation online oil-in-water (OiW) monitors may suffer from fouling of optics due to scales, soaps, emulsions, sludge, etc., resulting in inaccurate (usually low) concentrations.
New generation OiW monitors:
Yield more accurate O iW concentrations
Improve accuracy of the OiW measurements, allowing operators to optimize water treatment systems so that more product is recovered and less is re-injected or discharged into the environment.
Reduce operator maintenance and recalibration...
